Bug#945931: haskell-crypto: Removal notice: broken and unmaintained

[Ilias Tsitsimpis]

Source: haskell-crypto
Version: 4.2.5.1-9
Severity: grave
Justification: renders package unusable

This package is no longer maintained (last upstream upload in 2012). It
is also broken with GHC 8.6.4 and unlikely to ever be fixed (see [1]).

I intend to remove this package once ganeti has been updated to use
cryptonite instead (see [2]).
